One of the fun things to do is to place yourself in history either through your bloodlines or, in the academic world, through your professors and their professors back through time. While I had no PhD students, my students can still trace their "ancestry" back to 17th-Century France through me.
(There's more than one way, but this is the most reasonable one.)
